The purpose of this paper is to compare and evaluate the personal cloud storage products (PCSPs) in China and find the gap among them for promoting their service level. There are five representative products including Baidu cloud, Tencent cloud, Qihoo 360-cloud, Kingsoft cloud and Huawei DBank.

This study, first, extracts corresponding indicators based on the extant literature to evaluate PCSPs, and then collects the data about each index by investigation and the performance test, finally proposes a model to rank PCSPs, which applies analytic hierarchy process (AHP) to determine the indexed weights and the technique for order preference by similarity to ideal solution-grey relational analysis calculate evaluation score of each PCSP.

Among them, Qihoo 360-cloud gets the highest evaluation score contributed by large space, file editing and fast transmission speed. The rest are Kingsoft cloud, Baidu cloud, Huawei DBank and Tencent cloud in order. These storage products are all want of the addition or improvement of the online editing service similar as Google Docs.

AHP method is subjective, some of the data is incomplete, and some accidental error and systematic error exist in the actual testing process.

The findings can assist users in selecting more suitable products and offer cloud storage providers (CSPs) a general direction of improving their product performance.

Contributing to improve the overall level of the cloud storage services in China.

The study perfects the evaluation index system of the PCSP and fills the research gap in studying PCSPs in China, and expands the application field of the multiple criteria decision-making problems. This evaluation process and results have implied that CSPs in China should provide good services of large capacity, cooperation and security with the good internet environment of economical, high and stable speed by institutions and internet access providers.
